If we want to change the image size of our ComfyUI Stable Diffusion image generator, we have to type the width and height. First we calculate the ratios, or we use a text file where we prepared numbers which we can copy & paste. Either way, it stays a hassle. Not anymore though, there is a custom node called SDXL Aspect Ratio that enables us to simply select an image size from a dropdown list.
